FASTENER FOR ADJUSTABLE WINDOWS.

I To all whom it may concern Be it known that 1, JAN STOCH, a citizen ofPoland, residing at Uniontown, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inFasteners for Adjustable Windows, of which the following is aspecification. v

The main object of this invention is the provision of an adjustablewindow which ma be accurately regulated'to allow any deslred degree ofopening.

The above and other objects will become apparent in the descriptionbelow, in which like-named characters of reference refer to like-namedparts in the drawings.

Referring briefly to the drawings, Figure 1 is a perspective view of mydevice. I

Fig. 2 is an enlarged view, partly in section, of one of my adjustablesupports.

Fig. 3 is :another enlarged view of the same, partly in section, showingthe interior construction.

Fig. 4 is a cross-sectional view on the line 4-4 of Fig. 3.

Referring now in detail to the drawings, the numeral 1 represents awindow sash hav ing a window frame 2 horizontally hinged to the up erportion thereof, and a pair of window rames 3 vertically hinged to thelower portion thereof. I provide latches.4 of common construction forthe latter. Eyelets 6 are secured to the upper frame 2, and hook-likemembers 5 are pivotally secured in said eyelets, and are adapted toengage eyelets 7 on the sash 1.

A sleeve 6 surrounds, and is rigidly secured to, the member 5, and isprovided on the interior with a plurality of spaced apart notches 7. Asecond member 8 is-slidably mounted; within said sleeve, and is providedat its extremity with an extension 9 which engages the eyelet 7. Achannel extends through the member 8, and therein is slidably mounted arod 10 having an upwardly extending lip 11 by means of which the rod maybe moved in its channel. A recess 14 Specification of Letters Patent.

is provided in the member 8 near the forward end, and a mouth 12 isprovided about the channel where the latter enters said recess. Withinthis month, rigid with the rod 10, lies a flange 13. A lug 15 isvertically slidably mounted within the recess 14, and is provided with ahorizontally extended nose 16 having its upper surface curved after thefashion of a cam. A band spring 17 is secured within said recess and thefree end thereof engages a shoulder in the 111 15 and urges the latterupward into a notch 7*. It is apparent that, upon. forcing of the rod 10forward (to the left in Fig. 3), the

end of said rod, by engagement with the nose 16, will draw the lug 15from the notch 7" and thereby allow the member 8 to slide in the sleeve6. Said member 8 is thus 'moved into the desired position, and the rod10 is withdrawn, again allowin the lug 15 to enter another notch andretaining the member 8 securely in its new position relative to thesleeve 6. Thus the effective length of the member 5 may be varied atwill, and the degree of openin of the window 2 may be nicely regulate Iclaim:

A device of the class described comprisin in combination with a windowplvotal y attached to a sash, means for varying the degree of opening ofsaid window comprising a member pivotally attached to said window, asleeve rigid with said member, said sleeve having its interior surfacenotched, a second member slidable within said first-member, a channel insaid second member having a rod slidable therein, a recess near the endof said second member, a lug slidably mounted in said recess and havinga nose extending therefrom, means for urging said lug against saidsleeve, said rod being adapted to move said lug against the force ofsaid means when said rod is moved inward in said channel.

In'witness whereof I afiix my signature.
